摘要：
Sn-119 Mossbauer emission spectroscopy data demonstrate that the impurity tin atoms resulting from the radioactive decay of the Sb-119 isotope in the structure of glassy As (x) S1 - x and As (x) Se1 - x alloys reside on the arsenic site and act as two-electron amphoteric centers with a negative correlation energy: tetravalent six-coordinate tin acts as a singly ionized donor, and divalent three-coordinate tin, as a singly ionized acceptor.
